Three-dimensional printing is causing a huge buzz in the technology world, and was celebrated by Forbes as a potential world-changing invention. However, 3D printing isn’t printing in the traditional sense of ink on paper; to understand the close-to-perfected invention of 3D printing you’ll need to rethink “printing” as you know it.

How does 3D printing work?

Three-dimensional printing is based on the same basic concept as a 2D printer: ink is taken from a well in the printer and distributed onto the printed material. The printer in your home or office would stop here, but 3D printers take it to the next level — they distribute the material inside (usually a powdered material or liquid metal) layer by layer, and fuse each layer together with a laser.

What is 3D printing used for?

Many industries have found uses for 3D printing. Medical industries have especially embraced the new technology, benefiting from the ability to produce any item on location. 3D printers have produced human tissue, prosthetic limbs, and even a transplant-ready jawbone!

What is perhaps even more amazing is that creating architectural structures is now possible through 3D printing. Soon entire buildings will be able to be constructed via 3D printers, which could be utilized in disaster situations and everyday construction alike.

What is the future of 3D printing?

Three-dimensional printing faces several distinct avenues for growth in the future. The company Made In Space is experimenting with using 3D printers to produce materials in space, to relieve the amount of materials that astronauts carry with them into space. The U.S. Army already uses 3D printers to create spare parts for machines while in the field. The complete lack of excess material has made this technology very appealing to a several different industries.
